0700 Tuesday:
The Snapshot: Dry with high clouds moving in later today, a chance of snow tomorrow
night through Friday. Dry for most of the
weekend with snow possible Sunday night.
The Science: High cirrus clouds will move into today in
response to the shifting jet stream. NW flow will allow a weak low-pressure
system to roll down the BC coast bringing a little snow to the Cascade Mountains
starting tomorrow night. Light mixed rain and snow (mostly snow) with freezing
levels +-4000’ will continue into Friday morning. Storm totals are light with only a few inches
of snow likely.
Long Range: The precipitation
tapers off Friday with Saturday and Sunday trending dry, colder and partly
sunny. Another weak system may bring a
few more inches of snow late Sunday night into Monday.
